Mulgore - Ghost Howl Pathing
As the title states, Ghost Howl currently patrols Mulgore by floating under the world at higher elevations (eg, by the spirit rise elevators) , making it impossible to kill him until he makes it past the hill (above spirit rise on the map) wherein he then pops out of the ground and falls above the ground making it so that he must be pulled with a ranged attack.
